🔍 Key Concepts

• Transverse stability – how a vessel behaves side-to-side when weight is added or removed • Effect of removing weight on one side only (starboard vs port tanks) • Difference between trim (fore-and-aft) and list (sideways)

💭 Think About

• When you burn fuel, are you adding weight or removing weight from the side where the tanks are located? • If weight is removed from the starboard side only, which side will become lighter and which side heavier relative to the centerline? What does that do to the ship’s heel? • Which two choices relate to fore‑and‑aft change (bow vs stern), and which two relate to side‑to‑side change (port vs starboard)?

✅ Before You Answer

• Identify whether fuel consumption from side tanks mainly affects list (sideways) or trim (fore-and-aft). • Decide which way the vessel will lean when weight is removed from the starboard side only. • Eliminate all options that only describe fore-and-aft changes, since those are not caused by unequal port/starboard fuel use.
